Commercial Climate Control Systems

Make
sure your employees, customers and visitors are comfortable, with an efficient
A/c system.

We can undertake inspections, service and maintenance to ensure your
system runs as efficiently as possible. We can even undertake new installations
for buildings with no current HVAC system, or for new buildings or conversions.

Sometimes there are tax savings or grants available -at the very least,
having your system serviced will increase efficiency and reduce your energy
bills.

Domestic Aircon Systems

Sleepless nights on those hot, humid summer nights are no fun - why should
you suffer when for a relatively small investment you can control the
room temperature with a flick of a switch.

As well
as cooling, modern A/c units can provide instant heat as well. It does
this using a heat pump which extracts low temperature energy from the
environment and increases its temperature for heating purposes.

Heat pump systems are ecxtremely efficient, and can be 3 -5 times more efficient than normal fuel and are more than capable of warming a house completely, even during the lowest winter temperatures.

How Air Conditioning Works:

Keeping your building cool and regulating the temperature is important
during the summer months. A/C is perfect for performing such tasks. However,
most people don’t realize that an air conditioner performs a lot
more functions. High quality air conditioners use thermostats to make
sure your room enjoys optimum temperature.

In addition to this, modern air conditioners are also equipped with onboard
filters to remove particulates and dirt from the room, plus they can even
control humidity. The system is also responsible for effectively reducing
the moisture by significantly lowering the temperature.

Parts of An Air Conditioner

Every a/c system features four main parts. They work together to move
the air in your room in two different directions - Outside and Inside.
These parts are also responsible for managing the refrigerant in your
system.

Evaporator - It receives the liquid refrigerant.

Condenser - It facilitates heat transfer.

Expansion valve - It regulates the refrigerant flow to the evaporator.

Compressor - It pressurizes the refrigerant.

The evaporator is located on the cold side of the air conditioning system.
It features a high quality fan that constantly blows air over the coils.
Since these coils are chilled, they pass on cold air into your room. The
condenser and compressor are located on the hot side of the air conditioning.
They are also equipped with fans to send hot air outside the room.

There are two sets of coils that are kept apart with the expansion valve.
It is responsible for compressing the liquid refrigerant, and regulating
its flow. The liquid refrigerant enters the evaporator through valves,
timers and sensors. Thus, it gets converted back to gas.

The refrigerant gas is completely turned back to liquid with the compressor.
Most air con units feature many different valves, timers and sensors.
These four main parts are responsible for the proper functioning of the
aircon system.

How Air Conditioning Works?

A/C units work on the principle of refrigeration. Every air conditioner
has a special mechanism through which it forces chemical compounds to
properly evaporate and condense constantly. Such chemical compounds are
called refrigerants.

When temperatures are reduced, they change from one state to another.
In addition to this, air conditioners are also equipped with high quality
fans to cool the room by moving air over cold coils filled with refrigerant.

Similarly, hot air moves over low pressure, cold evaporator coils. Even
these coils are filled with refrigerants. Due to this, the refrigerant
liquid transforms into a gaseous state. In order to make sure your systems
cooling is inefficient, it keeps converting high quality refrigerant gas
to a liquid state, and vice versa.

It is important to understand that A/C systems are very complex machines.
Thus, you should only hire professional companies to handle installations,
repairs and maintenance.

Choosing the Right Size for Proper Functioning and Maximum Efficiency

Systems are available in many different sizes. Both split & window
air conditioning systems come in many different energy-saving ratings
and sizes.

While buying an a/c unit, you may not have an idea about the size of
system you need. It is always better to buy the right size, which can
efficiently cool the whole area. In this section, we will tell you how
to determine what size you need.

In order to determine the size you need to buy, there are certain simple
calculations. First of all, you have to multiply the length of the room
with its width. Once you have the answer, multiply it further with 25
BTU. This is a measurement for ample cooling in all kinds of weather including
hot, humid, sunny and rainy days.

For instance, if your room is 10 feet wide and 15 feet long, 12 x 15
will be 150 square feet. Now, multiply this number with 25 BTU, which
will give you the minimum BTU aircon unit that you need to buy. In this
example, you will have to buy a system with 3750 (150 x 25) BTU cooling
capacity.

Some people may be confused about a certain issue. They are not sure
if a smaller unit would be better, or if they should buy a larger one.
Let us answer your doubts about such issues.

Air conditioners with smaller BTU units will continue to run. They will
try to keep up and keep the area cool. As a result, your electricity bill
will be high. Moreover, such air conditioners are not very effective when
it comes to completely cooling the area.

On the other hand, an air conditioner can be an overkill if it’s
too large. Most of the people think that a larger air conditioner tends
to cool quickly. Although, there is nothing wrong with this notion, it
is important to understand that this will impede the basic reason for
running an air conditioner.

While cooling the room, a larger air conditioner will also extract moisture
from air, which will make you feel hot and sticky. The air being blown
from the air conditioning unit will be cooler. However, it will be unable
to properly extract moisture from air if it does not run long enough.
As a result, you will feel hot and sticky.

Therefore, the basic purpose of running an air conditioner in the room
will be defeated. Your whole skin will feel moist and you will just feel
better when cool air blows over it. Moreover, if you use an air conditioner
which is too large, it will turn off and on frequently.
